End result of the huge software of adaptive optical structures, an figuring out of optical wave propagation in randomly inhomogeneous media has develop into crucial, and a number of other numerical types of person AOS parts and of effective correction algorithms were constructed. This monograph comprises specific descriptions of the mathematical experiments that have been designed and conducted in the course of greater than a decade's worthy of research.

18). The precision of the simulation was verified by comparing the variance of the random realizations obtained with the variance calculated by Eq. 12). At L0 < 100R the difference did not exceed 5%, and at L0 > 100R it increased quickly because of the growing calculation error of the integral in Eq. 18). 4 Modification of the Numerical Model for Partially Coherent Beams In the preceding sections we considered propagation of coherent beams. However, the radiation divergence for real laser sources is always greater than the diffraction limit.
